More than 300 people, including students, faculty, professional scientists, engineers, policy-makers, consultants, and community members, participated in the twelfth annual Susquehanna River Symposium Nov. 10-11, 2017, at Bucknell University.

"The Spirit of Two Great Rivers: The Delaware and Susquehanna" drew participants from as far away as New York, New Jersey and Delaware for the two-day event. Friday featured a keynote address delivered by Mohawk spiritual leader Dr. Thomas Porter and more than 80 research posters by students and faculty from 16 universities.

On Saturday, Bucknell’s Elaine Langone Center continued to be a hub of activity with plenary presentations by Elizabeth Boyer, David Strayer, and Tom Porter who led hour-long breakout discussions afterwards. Everyone continued to fellowship over lunch in the Walls Lounge.

The afternoon featured twenty-two oral presentations in six different categories and exhibits from twelve companies and organizations. This year's symposium attracted a record number of participants from the general public.

Details about the symposium are provided in the 70-page Program with Abstracts, which includes a schedule of events and the author names, titles, and abstracts for each presentation.
